Eaton leverages cylinder deactivation and exhaust thermal management technologies to reduce commercial vehicle emissions

Green Car Congress

These agencies, in concert with other national and international regulators, seek to significantly reduce greenhouse gas (GHG) emissions and harmful air pollutants produced primarily by heavy-duty trucks, vans and buses. CDA technology can benefit vehicle manufacturers facing tightening emissions standards in Europe as well.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

There are widespread policy assumptions that the phase-out of gasoline and diesel internal combustion engines will over time lead to much reduced emissions of Volatile Organic Compounds (VOCs) from road transport and related fuels. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

Chalmers study: ban on sales of fossil-fuel cars greatly reduces lifecycle GHG mainly due to tailpipe emissions; risk of carbon leakage in manufacturing

Green Car Congress

The researchers considered emissions from the entire lifecycle—from the manufacture of electric cars and batteries, to electricity used for operation. A rapid and mandatory phasing in of electric cars could cause emissions from Swedish passenger cars’ exhausts to approach zero by 2045. —Johannes Morfeldt. 2021.102807.

WHO IARC classifies diesel exhaust as carcinogenic to humans (Group 1)

Green Car Congress

After a week-long meeting of an expert working group, the International Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), classified diesel engine exhaust (DEE) as carcinogenic to humans (Group 1), based on sufficient evidence that exposure is associated with an increased risk for lung cancer.

Westport and Scania preliminary testing shows H? HPDI delivers peak BTE of 51.5% at mid-load

Green Car Congress

Scania’s engine fulfils the strictest exhaust emission requirements with low fuel consumption and high torque. Hydrogen use in an internal combustion engine with our HPDI fuel system is an affordable pathway to employ a zero-carbon fuel using existing engine architecture and existing manufacturing infrastructure. —David M.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

Empa, together with FPT Motorenforschung AG Arbon, Politechnico di Milano, lubricant manufacturer Motorex and other partners, is exporing the use of DME as a fuel for heavy-duty engines. An electrically driven compressor for precise exhaust gas recirculation is also used. This is done via exhaust gas recirculation (EGR).
